Rescue the kid from park

A teacher was given in-charge to take care of the students. The teacher
took care with full responsibility. In spite of that, a kid went inside
a park, which is under construction. Since it is Sunday, no men are
working inside. As there is a forest at backside of the park, it was
electrically fenced. So, the teacher informed the guard. The guard is
none other than you. The guard is none other than you. Now, you need to
switch off the electrical circuit and then you need to search and rescue
the kid.
